atherosclerosis occurs when fatty material builds up in the arteries. what disease is caused by this blocking the coronary artery?

The disease caused when atherosclerosis blocks a coronary artery is a myocardial infarction , commonly called a heart attack.

What is happening?

When fatty plaques build up in the coronary arteries, they can narrow or suddenly block blood flow to part of the heart muscle.

If the artery becomes completely blocked by a clot forming on a ruptured plaque, that part of the heart muscle is starved of oxygen and begins to die, which is a myocardial infarction.

Related heart condition

• Long‑term narrowing of coronary arteries from atherosclerosis is called coronary artery disease (CAD).

• When that narrowing or a sudden clot fully blocks a coronary artery, the acute event is a heart attack (myocardial infarction).

So, in the context of your question, the specific disease name is myocardial infarction (heart attack) caused by atherosclerotic blockage of a coronary artery.
